Struct SurtrRenderer 

pub struct SurtrRenderer { /* private fields */ }

SurtrRenderer implements the high-performance GPU backend.

Implementations

impl SurtrRenderer

pub async fn forge(window: Arc<Window>) -> Self

Forge a new SurtrRenderer from a winit window.

pub fn begin_frame(&mut self) -> CommandEncoder

begin_frame — Strike the flaming sword to begin a new GPU frame.

pub fn end_frame(&mut self, encoder: CommandEncoder)

end_frame — Quench the blade by submitting the full Muspelheim multi-pass effect.

impl SurtrRenderer

pub fn fill_rect_with_mode(&mut self, rect: Rect, color: [f32; 4], mode: u32)

Converts a Rect in logical pixels into NDC and appends a quad. mode controls the fragment shader path: 0 = solid fill, 1 = glow/bloom.

impl Renderer for SurtrRenderer

fn fill_rect(&mut self, rect: Rect, color: [f32; 4])

fn fill_rounded_rect(&mut self, rect: Rect, _radius: f32, color: [f32; 4])

fn fill_ellipse(&mut self, rect: Rect, color: [f32; 4])

Fill an ellipse/circle that fits inside rect.

fn stroke_rect(&mut self, rect: Rect, color: [f32; 4], stroke_width: f32)

fn stroke_rounded_rect( &mut self, rect: Rect, _radius: f32, color: [f32; 4], stroke_width: f32, )

fn stroke_ellipse(&mut self, rect: Rect, color: [f32; 4], stroke_width: f32)

Stroke an ellipse/circle that fits inside rect.

fn draw_line( &mut self, x1: f32, y1: f32, x2: f32, y2: f32, color: [f32; 4], stroke_width: f32, )

Draw a straight line from (x1,y1) to (x2,y2).

fn draw_text(&mut self, _text: &str, x: f32, y: f32, size: f32, color: [f32; 4])

fn draw_texture(&mut self, _texture_id: u32, rect: Rect)

Draw a texture (GPU-side) at the specified rect.

fn draw_image(&mut self, _image_name: &str, rect: Rect)

Draw an image asset by name or path.

fn push_clip_rect(&mut self, rect: Rect)

Push a clip rectangle. All subsequent drawing is clipped to rect. Implementations that do not support clipping may ignore this call.

fn pop_clip_rect(&mut self)

Pop the most recently pushed clip rectangle.

fn push_opacity(&mut self, opacity: f32)

Set a global opacity multiplier applied to all subsequent draw calls until pop_opacity is called. opacity is in [0.0, 1.0].

fn pop_opacity(&mut self)

Restore the previous opacity level.
